Abstract

Abstract:

A formula for data dependent jitter (DDJ) is derived from the pulse response function of the high speed serial link. Based on the formula and mBnB encoding schemes, an iterative algorithm for finding the input bits which has the maximum or minimum of DDJ is presented and the peak-to-peak value of DDJ is calculated. Compared to the ordinary method of using lots of random mBnB coded bits to search for the peak-to-peak value of DDJ, this method is more accurate and with less computational complexity. The result can be used to evaluate the jitter performance of different mBnB coding schemes.

Key words: data dependent jitter, mBnB coding, 8B10B coding, 4B5B coding, pulse response
